1. A method for adjusting a scanning frequency of a touch screen, comprising: acquiring an ambient brightness when receiving an instruction to light up the touch screen; determining whether the ambient brightness is beyond a predefined ambient brightness range; and reducing the scanning frequency of the touch screen, when the ambient brightness is beyond the predefined ambient brightness range, wherein acquiring the ambient brightness comprises: acquiring a first brightness value by a first brightness sensor arranged on a first side of a mobile terminal where the touch screen is arranged; acquiring a second brightness value by a second brightness sensor arranged on a second side of the mobile terminal different from the first side; and determining the ambient brightness based on the acquired first and second brightness values, wherein the method further comprises: determining whether a glare occurs based on a brightness value acquired by the first brightness sensor, and reducing the scanning frequency of the touch screen when the glare occurs.
This invention relates to optimizing touch screen scanning frequency in mobile terminals to improve power efficiency and user experience. The problem addressed is excessive power consumption and potential touch detection errors caused by high scanning frequencies in bright or glare-prone environments. The method involves adjusting the touch screen's scanning frequency based on ambient brightness conditions. When an instruction to activate the touch screen is received, the system measures ambient brightness using two brightness sensors positioned on opposite sides of the mobile terminal. The first sensor captures a first brightness value, while the second sensor captures a second brightness value. The ambient brightness is then determined by analyzing these two values. If the calculated ambient brightness exceeds a predefined range, the scanning frequency of the touch screen is reduced to conserve power. Additionally, the system checks for glare conditions using the first brightness sensor. If glare is detected, the scanning frequency is further reduced to prevent touch detection inaccuracies caused by excessive ambient light interference. This approach ensures that the touch screen operates efficiently in varying lighting conditions, balancing power consumption with touch responsiveness.
2. The method of claim 1 , wherein reducing the scanning frequency of the touch screen comprises: acquiring an operation frequency of a user input in a predefined period before lighting up the touch screen, the predefined period comprising a time point when the instruction to light up the touch screen is received; determining whether the operation frequency is less than a predefined operation frequency threshold; and reducing the scanning frequency of the touch screen, when the operation frequency is less than the predefined operation frequency threshold.
A method for optimizing touch screen scanning frequency in electronic devices addresses the problem of excessive power consumption when the touch screen is inactive or lightly used. The method involves dynamically adjusting the scanning frequency of the touch screen based on user input activity to conserve power. Before lighting up the touch screen, the device acquires the operation frequency of user inputs within a predefined period, which includes the time when the instruction to light up the touch screen is received. The device then determines whether the operation frequency is below a predefined threshold. If the operation frequency is below the threshold, indicating low or no user interaction, the scanning frequency of the touch screen is reduced to minimize power usage. This adaptive approach ensures efficient power management while maintaining responsiveness when needed. The method may be part of a broader system for touch screen control, where the touch screen is initially in a low-power state and activated in response to specific conditions, such as detecting a user's presence or receiving an input signal. The dynamic adjustment of scanning frequency further enhances energy efficiency by reducing unnecessary touch screen operations during periods of inactivity.

A method for optimizing touch screen scanning in electronic devices addresses the problem of inefficient power consumption and performance degradation during high-frequency touch operations. The method involves dynamically adjusting the scanning frequency of a touch screen based on the detected operation frequency of touch inputs. When the operation frequency of touch inputs is below a predefined threshold, the touch screen is scanned at a reduced frequency to conserve power. Conversely, when the operation frequency meets or exceeds the predefined threshold, the touch screen is scanned at a normal scanning frequency to ensure accurate and responsive touch detection. This adaptive scanning approach balances power efficiency and performance, particularly in devices where touch inputs vary in frequency, such as smartphones, tablets, or interactive displays. The method may also include detecting touch inputs, determining the operation frequency of those inputs, and comparing the operation frequency to the predefined threshold to trigger the appropriate scanning mode.

The method involves acquiring brightness values from multiple sensors. A first brightness value is obtained from a primary sensor, such as a dedicated ambient light sensor, while a second brightness value is acquired from a secondary source, such as an image sensor or another light sensor. These values are then weighted based on their reliability or relevance to the current environment. The weighted values are summed to produce a composite ambient brightness measurement. This weighted sum is used to determine the final ambient brightness, which can then be applied to adjust display settings like brightness levels or color temperature. The weighting step ensures that more reliable or contextually appropriate brightness readings contribute more significantly to the final measurement. For example, if the primary sensor is temporarily obstructed, the secondary sensor's reading may be given higher weight. This approach improves accuracy and adaptability in varying lighting conditions. The method enhances user experience by providing more precise display adjustments while conserving power by avoiding unnecessary brightness changes.
